This study aims to analyze the characteristics of hydrocarbon chemicals in the Merdeka curriculum and curriculum 13, as well as explore variations of hydrocarbon materials taught by teachers in various schools under the Merdeka Curriculum. The type of research used is descriptive qualitative through survey methods. Respondents in this study involved 24 chemistry teachers who worked in DKI Jakarta and Yogyakarta. The selection of respondents was random. The results of this study show that there are differences in the characteristics of hydrocarbon materials taught in the 2013 curriculum and the Merdeka curriculum. In the Merdeka curriculum, most chemistry teachers still do not differ much from each other even though they have been given freedom in teaching, with only slight variations in the selection of the material. Teachers consider materials in hydrocarbon topics very important and must be taught thoroughly because they will be useful in learning the next topic. In making decisions to teach hydrocarbon material, teachers should increase their understanding of learning objectives, student heterogeneity, limited reference sources, school facilities, and students' initial knowledge.

Student concentration in learning chemistry tends to be low due to the abstract nature of the material and the dominance of teacher-centered approaches. Innovative, student-centered strategies and interactive media are needed to enhance engagement and focus. This study aims to investigate the improvement of student learning concentration through the "Everyone Is a Teacher Here" (EIATH) strategy assisted by Genially media. A quasi-experimental design with one-group pretest-posttest was used, involving 36 students from class XI MIPA II at a Jakarta senior high school, selected through purposive sampling. Student concentration was measured using a validated non-test instrument based on a Likert scale. Data were analyzed using normality and homogeneity tests, followed by a paired sample t-test. The results showed that the data were normally distributed (p = 0.200) and homogeneous (p = 0.204). The paired t-test indicated a significant improvement in student concentration (t = 73.3 > t table = 1.68957). However, the N-Gain score was 0.2, indicating a low level of improvement. Discussion: Although the EIATH strategy, assisted by Genially media, significantly enhanced student concentration, the low N-Gain score suggests that its implementation needs to be further optimized. The combination of active learning and interactive media holds potential but may require extended application and supportive classroom conditions to achieve higher impact. The "Everyone Is a Teacher Here" strategy, supported by Genially media, has a positive effect on improving student learning concentration in chemistry, but refinement in implementation is necessary to achieve more substantial outcomes
